Qoheleth says that if you love money, you will never have enough money to be satisfied. The same goes for wealth. You are never wealthy enough. No gain is enough. We see this all the time. The rich and wealthy never say that they have enough. They always want more. All this is vanity and useless. If you have more goods, there will be more people there to eat them up. What is the gain for the owner of this increase in food? He gets to watch others eat it up.
